The pivoted supporting yoke iently folded down to aneat posit-ion about arm 6is adjusted in a vertical plane the base of the automobile tire changer in I astride arched sector -7 and substantially themanner shown in the dotted lines repreheld in the desired position of adjustment senting the same. 7 by pin 8 insertediuholes 28- of the 50 Fig. 2 is a perspective showing in larger supporting arm -6 and through the de-,

Ratchet dog pivots on sleeve -3 at -2t. The base plate of the tirechanger on which the device at my invention is adapted to be used is indicated at -l;'l.

The operation of this device is simple and easy to understand and will be appreciated by those skilled in the art.

Assiuning that pneumatic tire --29-- has been placed in suitable position for removal from its supporting rim -30 the operator first places the tire removing" hook 1- in suitable position on top ot' the tire near the outer edge oi the supporting rim and then exerts a downward pressure on handle lever -2- with the pressure applied at hand grip -l7- thus causing the point -l8-- oi the hook to remove the clincher from the rim after the rim has been suitably prepared for such removal by the methods provided in the normal operation of tire changers oi the character illustrated in Figure --l-- for which Letters Patent have been previously applied.

After releasing the tire clincher in this manner from its run in one place the tire removing attachment may then be rotatably moved from place to place about the periphery oi the tire where from step to step a downward pressure is exerted against the the in all the necessary positions about the periphery ot' the tire to elicet a successful removal of the same from the supporting rim thereof.

In this connection particular attention is called to the fact that the tire removing attachment is adapted to be optionally rotated about the periphery of the tire through the rotatable action of collar supporting bracket -l 0- mounted on the leg of the tire changer; this being; a particular advantage in removing a tire due to fact that it cnables the operator to quite easily hold the ad *antages gained in the successive steps in, the tire removing operation.

It will be noted that this deviceis adapted to tires of various sizes and to those skilled in the art it willliie evident that certain minor changes may suggest themselves and such changes may be suitably made without departiiur from the spirit and scope of this invention or sacrificing any of its intended merits. 1

l-laving thus described the nature of my a pin passing through a hole in the yoke and holes in the sector, a lever pivoted to the yoke, a sleeve pivoted on the lever a spring pressed pawl pivoted to the sleeve and a hook having a] notched shank :u'ljustably engaged by the pawl and passing: through the sleeve.

Tu witness whereof. I hereunto set my hand this 15th dayof October. A. D. 11924.
